The rise of the great Alarm

When the space squirrels came to our world they found a dying people. A war scorched ruin with smoke still puffing toxic vapors. The damage was done and everyone was going to die. But the brains but we saved in jars we are slaved. Fed random life templates by the master computer The Great Alarm. The space squirrels meant well but they have moved on thousands of years ago and the machine is failing. The great alarm needs more and more energy it draws from the preserved living brains to keep together and it draws it from making our minds feel sadness, rage, pain and boredom. It eats these brainwaves and goes on another day.
